I don't know what kind of display this is. Is it a fixed frequency
or a multifrequency monitor? Can it only be driven by a special 
video card? If so, why?

Where does this card come from? Was it in use before you got it?
In which system? Can you get more information from the former
owner/user?

Any VGA compatible gfx-card should be useable with the
VGA-XServer. Is the console screen ok? What did the output
i.e. screen look like when you tried configuring it?
If it is a fixed frequency monitor, you must configure
the X-Server to use these certain frequencies the monitor
can handle.

I don't :-) Did you try an internet search to find more
details about the monitor?
